Abstract

The device comprises a hollow casing (1) inside which is mounted a reciprocally moving striker (2). The striker (2) is provided with calibrated grooves (3) which connect working and idle stroke chambers (8, 9). For additional connection of the chambers (8, 9) by-pass channels (10, 11) are provided in the lower part of the casing (1), said channels serving for pressure regulation inside the casing (1) of the device.
